Increasing the amount of concurrent mailbox moves in Exchange 2010

Exchange 2010, by default, allows you to do 2 concurrent mailbox moves. This is a rather conservative approach, in this age of 10Gb Ethernet and super-fast SAN storage. Fortunately Microsoft has provided a mechanism whereby we can increase the amount of concurrent moves allowed.

Said mechanism involves editing the MSExchangeMailboReplication.exe.config file, which resides under the C:\Program Files\Microsoft\Exchange Server\V14\Bin\ foler.

These are the changes you need to make if you’d want to allow 20 concurrent moves:

MaxActiveMovesPerSourceMDB = “20"

MaxActiveMovesPerTargetMDB = “20"

MaxActiveMovesPerTargetServer = “20"

Once you’ve made the changes you will also need to restart the Microsoft Exchange Replication service. Lastly – all the above needs to be done on the target server.

About This Blog

This blog serves 2 purposes. Firstly, I want to share information with other IT pros about the technologies we work with and how to solve problems we often face. I work with technologies from the desktop to the data center, Active Directory, System Center, Exchange, Hyper-V, VMware, Networking and Storage.

Less altruistically, I use my blog as a reference. There's so much to learn and remember in our field that it's impossible to keep up. By blogging, I have a notebook that I can access from anywhere. It has made me look much smarter than I probably am on many occasions.
